Mark Wise paper

BBU starting point and expansion Look at 2.24 and 2.26 to see difference between kinetic and pole scheme in hep-ph/

Former Analysis extended Novosibirsk function: Argus function: Source Babar doc where: m 0 is peak position, σ is width, τ is tail parameter Source Phys. Lett. B 241, 278 (1990) where a and b are parameters to be fit

Y(3S) and Such Properties Width = /- 2.5 MeV (hbar = 6.58 x 10^-16 eVs) Liftime = 3.2 x 10 ^-23 s BBbar decay > 96% of the time (PDG)

SVT Extended Best angular information comes from inner points, not subject to multiple scattering. Particles with p_t less than 100MeV/c don’t make the drift chamber, and only with p_t > 120 MeV/c is the drift chamber reliable. Goal of 70% eff. In tracking information for MeV/c particles Coverage is between 20.1 and degrees. 5 Layers, double sided, inside (junction side) measures z, outside measures phi for first 3 layers, opposite for last 2. ~150,000 channels Inner 3 layers for measuring impact parameters, outer two for pattern recognition and low p_t tracking.

SVT Extended dE/dx formula for charged particles (from infn): Bethe-Bloch formula MC simulation of SVT (source Babar doc).

DCH Extended AUVAUVAUVA arrangement of the superlayers (10), each consisting of 4 layers. Axial (A) and stereo (U,V) 1.08%X0 at normal incidence dE/dx from ionization loss

DIRC extended Cherenkov Angle relation: Forward end has a mirror to reflect forward propagating photons Index of refraction for fused silica = 1.473

EMC extended 15.8 to o polar angle coverage (90% CM coverage) Energy resolution described empirically by: where a represents fluctuations in photon statistics and electronic noise, and b, constant term, comes from non-uniformity in light collection, influence of material in front, and calibration uncertainty Ultimately, a = 2.32% and b = 1.85% Radiation length, corresponding to the length for an electron to drop to 1/e it’s energy, or 7/9 the mean free path for pair production of a photon.

EMC Extended Source photon for low energy calibration from the process: 19 F + n → 16 N + α, 16 N → 16 O* + β, 16 O* → 16 O + γ

IFR Extended 21 active detector layers in the barrel, 18 in the endcaps Bakelite sheet bulk resistivity is 10^11 – 10^12 ohm cm Gas: 56.7% Argon, 38.8% Freon 134a, and 4.5% isobutane Graphite surfaces connected to ~8kV and ground.

IFR Extended LST
